Keep the Ultimate 2 Wireless current with 8BitDo Ultimate Software V2 (Windows/macOS only — there is no mobile updater). Plug the controller in over USB-C, launch the app, and apply the offered firmware. Updates add features like Switch mode and Switch 2 support and fix dongle-recognition issues. Don't disconnect mid-update.
